Voltage question

wazzledoozle · Jan 5, 2005, 04:10 AM

I was looking in my bios pc health status, and the -12v line is running at 13.51 while the +12v is running at 12.03
Is this a sign of a bad powersupply?

nay, i'm running my mobo for almost 2 yrs; bios says i have -13V but it works fine... ill give you a word if it gets cooked eventually

mayB the sensors are sending a bad info, example my cpu temp jumps from 16C to 63C almost every second (and the heatsink feels like hell but it runs so who cares

)

If you have a spare power supply, chuck it in and check to see if it varies a whole hell of a lot, if not, don't worry about it.

12.03 is waaaaay in spec; the -12 isnt really used by anything or the mobo sensor could just be off the deep end

True enough

I just had motherboard die so I was wondering if it was related...

Not likely, but it is possible, that voltage wasn't off enough to have caused any issues.
